Went on a trip up to the lakes in North West Iowa this weekend.. 300+ mile round trip, and I dont know what the hell was different about this trip than any other Ive ever taken in my truck, but I got 17 mpg.
The only thing ive recently done is the Sea Foam treatment, but that was 3 weeks ago. This trip as all hills too!
Hopefully I can keep this kind of MPG up

 

The gods of gasoline must have been smiling upon you that trip or something! maybe they will look up to wisconsin soon too.......
